I cannot agree more.

Also, I doubt that you are doing the right thing eating stevia and foregoing fruit. Stevia still contains carbs, even though it does not contain calories. With fruit, you get HYDRATION, which always helps - see above, plus FIBER, which binds sugar, plus vitamins and other good stuff, and you feel full. Stevia does not do any of that for you - it just makes the taste sweet. I dropped it in favor of real fruit.

I also need to lose 80 lbs after having lost 10 lbs, but I am hopeful that I will lost at least some if not all the way. But I do much more exercise than you do, and my skin looks tight and toned. If you could add swimming, go for it - in my experience it does wonders to skin tone.
